Hoplite

No matter how skilled you get, there is only so much you can do alone. If you lean to work with other, the limits are endless. Those who stand together stand strong. 

Phalanx formation

At level 3, while you are 5ft from an ally & utilizing a shield, you grant them and you a bonus to your AC equal to 1/2 your PB & can choose which of you get your shield AC bonus at the start of your turn, though you can switch has the extra AC as a reaction one of you being targeted for an attack (before you know if it hit). You both have advantage on STR checks & saves.

 

Wield Your Weapon

While wielding a shield, you can wield a 2-handed weapon with 1 hand, but you will have disadvantage with attack rolls.

Troop Tactics

At level 10, You & any allies within a 5 ft radius have advantage against any enemies that are 5 ft away from both of you and neither of you are incapacitated.

Held Position

At level 15, if you do not move during your turn, you can make 2 attacks as a bonus action as well a reaction to an enemy entering your melee range.

United Stand

At level 18, you have a number of charges within you = to your Fighter level. As a reaction to you or any ally within 30 ft that is adjacent to make a saving throw, you can send a number of charges to give those allies (&/or you) advantage on their saving throw = to the people being given advantage. You regain all spent charges after a short rest.
